This weekend, I plan to replace my master cylinder and Power Brake Booster. From what I read, the attachment bolts are under the dash and need to be removed from the inside.
 
Has anyone done this lately and are there any tips and things that I need to be aware of?

Ive replaced my master but never the booster.  From the posts here I've decided that when the booster has to be replace, Im going to farm it out to my corvette mechanic.  I have looked around under the dash,  after removing the drivers seat, and found that a man of my age and weight is not supposed to be in such positions for extended periods of time and bifocals don't help any either.  Seriously, the booster is supposed to be one of the most difficult jobs on the vette, right up there with heater cores.  Someone here will jump in who has done the repair with some specific pointers, Im sure.  From what Ive read an assortment of ratchet extensions  and a swivel joint are needed for the top nuts.  A little duct tape on the swivel joint will allow it to swivel but still stiff enough to guide onto the nuts.

I replaced mine about 6 months or so ago. Mine is a 72 so it should be about the same. Like Crossfire said an assortment of extensions and a swivel will get it done. I would squirt a little PB Blaster or something on them ahead of time because mine were very hard coming off. Maybe see if the wife has a couple muscle relaxers around for that night after taking it off so you can rest your tired and sore back. Just take your time and you can do it.

I'm sure we have something in the archives on the subject. I'll take a look.

Patience, being able to contort your body, removing the seats and the swivels help.  You will have to drop your steering column, etc.  Be sure you clean and shoot some type of electrical connector spray on those connectors and check everything, turn signals, brakes, etc, before you button her up.

I didn't check everything closely and had to drop the column again to get the connectors in properly and working properly.

Expect to spend a 1 1/2day to possibly 2 days.  It wasn't easy, but you can do it!

I'm glad I asked the questions. I had to chuckle at some of the comments, because I too have bifocals and have found out that when working in cramped close quarters that 2.5 times reading glasses are best. I'm really looking forward to this task!!??
 
Anyways, I'm redoing the brakes so I figure I might as well replace the booster while I'm at it.

I replaced the brake booster, that was a real job. Removing the neutral safety switch was pretty easy, but getting it back in there was tough. My back is sore from laying in a contorted position. Anyways brakes work fine now.

I did mine, removing the seat helped and having swivels with extensions are a must. The top left nut will be the toughest.

ok, glad we have these forums.  Have 3 nuts off the power booster and the push rod disconnected no way could I see that 4th one so had to double check to make sure there was a 4th.  Back out I go to find that 4th, it is one of the lower ones that I haven't found. I did not find the first 3 to be that hard, but I have the seat out and I am only 5'4" so that would make it a little easier. you just have to get comfortable and hang your feet out over into the trunk area, my biggest problem was keeping my hair from getting tangled in stuff getting in and out.  (I always seem to forget something I might need while I'm under there.)  Here's hoping I can spot that 4th one. I too have progressive lenses so working in such close quarters has been quite challenging.

Cindy, I had to chuckle when I read the part about getting your hair tangled in stuff under the dash.  That is certainly a problem that I didn't have; perhaps in my younger days but not now... Good luck with the 4th nut, it is lurking under there somewhere.

2011, Mid AmericaC3Fest/C3VR Gathering.....parking lot repairs...dark...and here's Barb installing the little clip that holds the booster rod to the pedal. She was the only one in the group small enough to fit up in there, and by golly, she got the job done. Wink
There is always one nut that is a pita to get to. Patience, and some swivel sockets will help...and a bright light.Thumbs Up

ok guys now I need some help.  The ever elusive nut, higher right side, still haven't been able to locate it.  I'm assuming the bolt pattern on the booster is equally spaced in a square or is the higher right side perhaps offset, tried getting fingers in there to feel around for it but still no luck. Doesn't help that the finger I smashed is on that hand and if anything even rubs it those little black words just sorta rush from my mouth.
